we've only had them since Sunday so all very new... they are partly litter trained, as in they use it 50% of the time. I've just discovered the source of the smell, they've been crapping in the back of the fireplace.
Not the worst place they could go for sure as it's brick and I can clean it easily... but how do I teach them to go in the tray 100% of the time?
Also should I put tin foil down at the back of the fireplace?
Thanks
